Product details
Overview
ADM810LAKSZ-REEL7 from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 4.63 V reset threshold, and operation down to 1.0 V VCC. It provides 240 ms (typical) power-on reset timeout, consumes 17 μA typical supply current, and is qualified for −40°C to +125°C industrial/automotive environments. It monitors 5 V supply rails in embedded controllers and intelligent instruments.
For engineers reviewing the ADM810LAKSZ-REEL7 datasheet, ADM810LAKSZ-REEL7 pinout, ADM810LAKSZ-REEL7 application, or ADM810LAKSZ-REEL7 equivalent, key selection criteria include reset polarity (active-high), SC70-3 package compatibility, guaranteed operation at VCC ≥ 1.0 V, and temperature-stable 4.63 V threshold with ±3.2% max deviation over −40°C to +125°C.
Technical Context
The ADM810LAKSZ-REEL7 integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timer. Its reference circuit maintains accuracy across temperature, enabling reliable brownout detection even during fast transients on VCC.
It features a push-pull RESET output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min) and sinking 1.2 mA at VTH(min), eliminating need for external pull-up resistors. The device operates continuously as VCC falls to 1.0 V, ensuring deterministic reset assertion through deep undervoltage conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63 V (nominal); ±3.2% tolerance over −40°C to +125°C - ensures stable 5 V rail monitoring without false resets |
| Reset Polarity | Active-high push-pull output - directly interfaces CMOS inputs without pull-up resistor or level-shifting |
| Reset Timeout | 240 ms typical after VCC rises above threshold - holds microprocessor in reset until power stabilizes |
| Supply Current | 17 μA typical at VCC < 3.6 V - enables use in battery-powered and low-power embedded systems |
| VCC Operating Range | 1.0 V to 5.5 V - guarantees reset assertion down to near-zero supply, critical for graceful shutdown |
| Temperature Range | −40°C to +125°C - supports under-hood automotive, industrial control, and harsh-environment applications |
| Package | 3-Lead SC70 (KS-3) - 2.0 mm × 2.1 mm footprint, compatible with high-density PCB layouts |
Pinout & Package
ADM810LAKSZ-REEL7 uses a 3-lead SC70 (KS-3) package with 0.65 mm pitch, 0.10 mm coplanarity, and JEDEC-compliant outline per Figure 15.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Monitored supply input - connects directly to 5 V rail; device remains functional down to 1.0 V |
| 2 | RESET | Active-high push-pull output - drives high during normal operation, pulls low only during reset assertion |
| 3 | GND | Ground reference - must be connected to system ground plane for accurate threshold sensing |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune comparator | Rejects transients ≤ 100 μs duration at VTH – VCC = 100 mV - prevents spurious resets from supply noise |
| Low-voltage operation | Functional reset assertion at VCC ≥ 1.0 V - ensures deterministic behavior during brownout and power-down |
| Precision threshold | 4.63 V ±0.15 V over full temperature range - eliminates need for external trimming in 5 V systems |
| Push-pull output | No external pull-up required - reduces BOM count and simplifies layout vs. open-drain alternatives |
| Ultra-low quiescent current | 17 μA typical - extends battery life in portable instrumentation and remote sensors |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SEUR+T | 4.63 V threshold, SOT-23-3, active-low open-drain output, 1.2 μA max supply current | Requires external pull-up; incompatible with active-high logic interfaces without inversion | Select when board already uses open-drain reset architecture and lowest possible quiescent current is critical |
| TPS3808G33DBVR | 3.3 V threshold, SOT-23-6, adjustable delay, 1.1 μA typical supply current, active-low push-pull | Fixed 3.3 V threshold - unsuitable for 5 V rail monitoring without external divider | Choose only if redesigning for 3.3 V systems and programmable timeout is required |
Compared with MAX809SEUR+T and TPS3808G33DBVR, ADM810LAKSZ-REEL7 uniquely delivers active-high push-pull output at 4.63 V in SC70-3, eliminating external components while maintaining full 5 V rail compatibility and −40°C to +125°C operation - making it optimal for space-constrained, high-reliability 5 V microcontroller supervision.

FAQ
What is the reset polarity and output type of ADM810LAKSZ-REEL7?
The ADM810LAKSZ-REEL7 features an active-high push-pull RESET output. Unlike open-drain variants (e.g., ADM803), it does not require an external pull-up resistor. This allows direct connection to CMOS inputs and simplifies interface design in 5 V microcontroller systems where active-high reset is required by the host processor.
What is the exact reset threshold voltage and its tolerance over temperature for ADM810LAKSZ-REEL7?
The ADM810LAKSZ-REEL7 has a nominal reset threshold of 4.63 V. Over the full −40°C to +125°C operating range, the threshold remains within 4.44 V to 4.82 V (±3.2% of nominal), as specified in Table 1 of the ADM803/ADM809/ADM810 datasheet Rev. I. This stability ensures reliable 5 V rail supervision without false triggering.
Does ADM810LAKSZ-REEL7 remain functional at low supply voltages?
Yes, ADM810LAKSZ-REEL7 asserts RESET down to VCC = 1.0 V and remains operational across the full 1.0 V to 5.5 V supply range. Its internal circuitry continues monitoring and timing functions even during deep brownout, guaranteeing deterministic reset behavior - a key differentiator versus supervisory ICs that disable below ~2.5 V.
What package and footprint does ADM810LAKSZ-REEL7 use?
ADM810LAKSZ-REEL7 is packaged in a 3-lead SC70 (JEDEC KS-3), measuring 2.0 mm × 2.1 mm with 0.65 mm lead pitch. This compact, RoHS-compliant package supports high-density PCB layouts and reflow soldering per JEDEC J-STD-020. Pin 1 is VCC, Pin 2 is RESET, and Pin 3 is GND - confirmed in Figure 4 and Table 4 of the datasheet.
How does the 240 ms reset timeout of ADM810LAKSZ-REEL7 improve system reliability?
The 240 ms (typical) power-on reset timeout in ADM810LAKSZ-REEL7 ensures the microcontroller remains held in reset until the 5 V supply has fully stabilized and internal clocks have settled. This prevents premature code execution, memory corruption, or peripheral misconfiguration - especially critical in systems with slow-ramping supplies or large decoupling capacitance.
